IMPROVEMENT IN HIKING-APPARATUS FOB. COLOR-PRINTING.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, JOSHUA HUNT, of Richmond, in the county oi' Wayne, and State of Indiana., have invented a. new and useful Improvement in Apparatus for Printing in more than one Color; and I do hereby declare that the fol-lowing is a. full, clear, and exact description ofthe some, reference being had to the annexed drawings, making part of this specification, in which- Figurel is n. perspective view.

Figure 2 is a. vertical transverse section.

Figure 3 is a plan.

The some letters inail the iiguresere used to indicate the same parts.

My improvement relates to un apparatus for printing, in more than one color,jobs in which'the letter-press portion of. the job is printed in several colors, and n. border is printed i-n one color.

'My invention consistsin combining, with the type-bed of a. press, two forms, one form to be printed in several colors, and the other to be printed in only one color, and inking-rollers so arranged that the several' inks shall be disposed in bends upon the roller or portion of a. roller, by which the varicolored inks' are to be 'transferr'cd to the lines of type, and a. single color be transferred to the roller or portion of e. roller from which the other form is to receive its ink, so that hy'nsing a. double sheet, and reversing it, or changingthe posit-ion of the forms after ope impression is taken, two complete jobs may be printed at two impressions.

The following description will'enable persons skilled in the art to construct and operate n1y improved apparatus. V l

In the annexed drawings, A is the bed of the press, on which the type-bed B slides in grooves, receiving a. reciprocating motion in the ordinary manner.i This bed is formed to receive two forms, C an'd D, of which the former contains that e intended to rint the letterress art ofthe 'ob, andthe other is the border, theforms .YP P P P J being placed successively on the bed, as shown.

It is desirablmto print the border in one color, while the type receives several colors. I employ for thisI purpose two independent sets of' rollers. One set of distributing-rollers E are constructed upon the plan set forth in George W. Wood's 1nd Wood and Ba-yliss patent. Each distributing-roller receives a. single color, which it transfers to the type-hiking roller E'. The ink thus received in bends upon the type-hiking roller is trensferred to the type according to the design, nsthe type, in passing, uro brought into contact with the inkingroller E. The border to be printed in one color receives that color from o type-inliing roller, G', which receives afsinglc color along its entire length freni the disth'ihuting-roller Gr.

In order that euch type-inking roller may come into contact only, with its own proper forni, the journals oi' 1 the rollers E and E' are :ill set in one sliding i'rnme F, which nieves freely, vertically, in dove-tailed grooves in the side standards K. The journnis of the rollers G und G' are in like manner set in n similarly-arranged frnnie, II.V Two parallel enne-tracks, I I', ure attached to the side of thc type-bed B. There are Wheels on the ends of the rollers G, in line with the truck I, :rnd other wheels on the roller E', opposite the truck I'. The tracks :ire cut exray alternately, cach along cnedinli' the length of its farce, so that a-s the bed-plete B moves towards the roller, the raised portion of the track I', encountering the wheel on the roilcr E', the latter and the other relier of that set,nttnched to the same sliding freine, will oc raised, and the border-form will pass under the roller E without touching the seine. As soon :is this form hes passed, the Wheels on the roller E drop on to the lower portion of the track I', which brings this roller upon the fece of the typo to be printed in .several colors. The reverse notion takes piece withrcg'ard to the border-forni; The roller G is allowed to bed D, the two forms :irc inked. An impress como in contact with it, while the roller E" is raised above it. In this manner, at one movement of the typen is thon teken on u sheet of double the intended size, on one end of which will he printed the letter-prees portion of thejob, und on` the other :L border. The forms: are `then to ne again inked, and the sheet reversed, :rnd another impression printed. sotha-t the letter-press Work shall be printed within thebla'nli border of the lrstimipression, and the border be printed .around the letter-press work. In this manner two 'complete jobs may be printed at two impressions. f

It maybe desirable to set up part of the type for theletter-press in the same form with the border, where such part of the job is to be in the same color with the border. In snch case, when the sheets have been run through once, theforms are to he reversed on the type-bemand the cam-tracks, which must be made adjustable, changed se as to reverse the order of action on the rollers. y

My invention is disting'iished from all other hiking-apparatus in this, that I combine in one apparatus twov type-inking rollers or portions of rollers, one of which receives the color in bands, and the other receives a single color, whereby I am enabled to print borders in one color, and letter-press in several colors, making only the same number of impressions as there are tobe inished sheets of the job printed. A

In Woods, and Wood and Baylies, and Baylies apparatus, there are onl5r the type-inking rollers arranged to receive the color in bands, and with that apparatus it is impossible to print the borders in one color at one imprcssio n,.with the letter-press in colors. v

' .In Montagns apparatus, as many forms of type are required as there are to be colors in the job when inished. v 1

' Printing'in t\\'o colors, at'two impressions, 'by reversing the sheet after making one impressiomris not'new; but in such ease the type for the letter-press is subdivided into different forms, and no provision made for printing the letter-press at one impression in several colors and the border in one color. In that, as in Montagus,'ea0h form receives but one color. I

The novelty in my improvement is in the combination which enables me to print the letter-press part of the job at one impression in several colors, and at the same time to print the border in one color.

WhatI claim'as my invention7 and desire to secure by Letters Patent, "is- The combination ot' the type-bed B, the two forms, and the type-inking rollers Elr G', and the adjustable cam-tracks I I", when so constructed and arranged in relation to the ink-distributing` rollers, that dilferent-eolored inks, first disposed in bands on the type-inking roller, or on part thereof, shall be transferred simultaneously to the'lines of type, and a single color bel also transferred to the other form, so that by two impressions, the sheet o'r the form being reversed, two completed jobs may be printed in which the letter-press is printed in more than two colors, and the border in one color, substantially 'as set forth.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.

' JOSHUA HUNT.
